Fel-Pro timing cover gasket and seal kit for Later LT engines found in 1995-96 F-body and Corvette and all B-body vehicles. This kit fits LT engines that came with a vented style opti which uses a larger seal in the center of the timing cover because the opti is driven by the dowel pin on the camshaft as opposed to a splined shaft used in the earlier design.
Fel-Pro Timing Cover Gaskets are engineered to deliver a perfect seal on every engine. That is why virtually every NHRA Drag Racing and NASCAR Cup Series teams - as well as a vast majority of professional engine rebuilders and vehicle service technicians - choose Fel-Pro over every other gasket brand.
